Write the equation x2 + 6x + y2 – 8y = 19 in standard form. Question 11 options:

1)
(x + 3)2 + (y – 4)2 = 44

2)
(x + 3)2 + (y – 4)2 =

3)
(x – 3)2 + (y – 4)2 =

4)
(x + 3)2 + (y + 4)2 = 44

i think this could be a possible answer (1 / 84) -1

good luck! : d

the 4th choice is the correct one

step-by-step explanation:

the answers are in the images, i received 100% on this assignment. hope this !

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
